It was designed in 1908 by the Supervising Architect's office under James Knox Taylor and built in 1909-10.","why_significant":"The nomination argues local significance in architecture, art and politics/government. It is a refined example of the classicism used by the Treasury's Supervising Architect's office in the early 20th century, and probably the finest early public building in Eureka. It holds the city's only 1937 federally sponsored tempera murals, and it was Eureka's first federal building.","narrative":"Standing on a raised foundation at Fifth and H Streets in downtown Eureka, this three-story federal building combines a post office, courtroom and government offices. Designed in 1908 by the Treasury Department's Supervising Architect's office under James Knox Taylor, it was built in 1909-10 and opened in early 1911. Its steel frame is clad in pressed brick, with a limestone base, a terra cotta cornice and five tall round-arched windows across the front. Inside, the first-floor lobby keeps its tile floor, marble wainscoting and original post office boxes, while a two-story courtroom rises above. Tempera murals painted in 1937 under Treasury sponsorship remain in place and are the only ones of their kind in Eureka. The building was the city's first federal building, requested by the Humboldt Chamber of Commerce from 1896. It is regarded as a refined, well-preserved example of early twentieth-century classical public architecture in the region and a landmark of the downtown core.","period_of_significance":"1900-","architect_builder":"James Knox Taylor, Supervising Architect","architectural_style":"Neoclassical (eclectic classicism, Beaux Arts influenced)","criteria":[],"status_note":"Occupied and in good condition.
